10c kWh
There is a lot to comment on your post, but this tiny part here is the most important, you should not be mining with such power rate, unless you get your hands on some miner made by aliens which beats all the odds that us as humans know.
You see, mining is like going to a war , while huge farms in china get 1-4 cents power and you pay 10 cents , it's like going to a war with a wooden stick and expect to win, also what makes that stick even less effective is the fact that you pay more tax / tariff and a lot on shipping , those guys can buy thousands of gears for much less than the price advertised, and they can move a dozen miner for less than 500$ , hire 100 Chinese workers to get that farm up and running ,pay them 10% the money you need to pay 10 of your people, and probably less than you pay your wife to reboot that laggy S17 when you are not around.
Let's dig a little deeper and see how things work for me vs someone else who pay a lot for power.
I pay 0 cents per kwh ( yes no typos ) , thanks to Satoshi who invented the difficulty adjustment concept, all I have to compete against is the lifespan of my gears, as long as my gears are up and running, I make money ,BTC price goes up or goes down or even Bitmain produces a new gear that does 10w a th tomorrow, all that does not really matter much because in the grand scheme of things i will always profit.
Joe pay 10 cents per kw, he has to compete against , me , the guy who pays 1 cent , the guys who pay 2,3,4,5,6,7,8,9 cents , price , difficulty and his wife for emptying that bank account of theirs.
I along side with those who have pretty cheap power rate will always make Joe's life harder , because we have a lot of room and willing to squeeze that last penny out of mining, we make decent profit and can always add more gears, even if prices are collapsing, we know that Joe will be liquidated and we get to buy his gears for really cheap.
Mining is no longer a hobby, no longer a get-rich over a month thing, it's getting more and more difficult , and regardless of how promising it looks , it's nothing but dominoes falling, if you are standing somewhere in the front, you will fall first, very simple.
we know that a lot of Chinese miners can get as low as 1 cent per kwh in some areas Xinjiang during rainy seasons and enjoy that power rate for 6-7 months , we know that in other regions in china as well as a lot of other countries , miners can get 4 cents per kwh , let's ignore the first group , and focus only on the second one,if your power rate is not pretty close to those guys , your chances are slim and your only hope is a fast price increase that surpasses the speed of adding more gears into the network.
Having said all that, if your power rate is pretty close to average say 5 to 6 cents at most , and you know when to buy a gear and how like phill explained, with a bit of "luck" you will make some profit.
IF BTC and indeed all crypto is to survive this miner capitulation and next years halving of BTC difficulty, etc. Someday/Somehow BTC MUST get over $10,000 with adoption and mining and stuff will have corrected itself etc or we are all fricking doomed.
If by survive you mean just survive, then bitcoin does not have to be over 10k when the halving comes, it will survive even at 100$ , yes more miners than usual will have to leave the game, bitcoin will be more subject to 51% attacks, but there will always be someone who is able to keep the blockchain alive as long as bitcoin is anything above flat 0.
